A plot has been uncovered wherein Iran was planning to assassinate the Saudi Ambassador to the US in Washington, DC. The Iranians (one a US citizen) charged with the planning dealt with an undercover agent posing as a member of a Mexican drug cartel and was offered $1.5 million to do the job. This will only serve Saudi Arabia to become even more agitated with Iran, along with the other Arab countries. There was mention that the assassination would take place by placing a bomb in a restaurant which would result in many lives lost, which would probably include other dignitaries. There was also mention on the news that there was a plan to bomb the Saudi embassy, as well as the Israeli embassy in Washington.
Of course Iran is denying it.
The US said that Iran would be held accountable for their actions: attempting to assassinate a diplomat on US soil. One analyst stated that the US has military based in countries that surround Iran. This could prove very interesting.
